Abstract
A device and method for maintaining and restoring normal curvature of a person's lumbar spine. The device is of non-deformable material, has a base lying in a plane and an upper surface curved in the direction of the sagittal plane to conform to the normal curvature of a person's lumbar spine. The curvature is preferably circular with a radius of between 14 and 20 centimeters, but generally approximately 17 centimeters and the base preferably extends in the direction of the sagittal plane for approximately 17 centimeters. The method of maintaining and restoring the normal curvature of the lumbar spine includes placing the device between a firm surface and the person's lumbar spine and preferably elevating the person's legs 12 to 18 inches for a finite period of time.
